6712SR Refrigerated Sampler
Section 5 Extended Programming
5-27
5.14 Pauses/Resumes
Pause and resume settings, available in extended programming,
create an intermittent sampling schedule. A program with
pauses and resumes begins sampling at its programmed start
time, continuing until the first pause time and day of the week. It
then suspends sampling until the first resume time, when it
begins sampling again. If the start time falls within a pause
period, the sampler will not begin sampling until the next
resume time. Pauses and resumes repeat weekly.
You can enter up to nine pairs of pause and resume times. The
pause and resume times shown as examples to the left suspend
the program between 5:00 p.m. Monday and 8:00 a.m. on
Tuesday and between 5:00 p.m. Tuesday and 8:00 a.m. on
Wednesday. If the start time is Monday at 8:00 a.m., the sampler
takes samples between 8:00 a.m. and 5:00 p.m. Monday; between
8:00 a.m. and 5:00 p.m. Tuesday; and, continues after 8:00 a.m.
Wednesday. To remove pause and resume settings from a
program, select CLEAR.
A sampler running a pause/resume program resets the pacing
interval at each resume time. You can program the sampler to
take a sample at resume times (see screen at left).
5.15 Running Programs To run an extended program, select run from the main menu.
You may also select YES at the RUN THIS PROGRAM NOW?
screen at the end of the programming screens.
Extended programs scheduled to start at a clock time will not
start until the programmed clock time on or after the first valid
date.
Note that if you have recently calibrated a parameter probe, the
sampler may delay the start and display “PLEASE WAIT” until
valid readings are expected from the probe. The delay accounts
for the time typically required to install the probe, and lasts for
five minutes after you complete the calibration.
5.15.1 Run Time Screens Run time screens, which report the program’s status while
running a program, are explained in Section 4.
5.15.2 Interrupting a
Running Program
Interrupting a running program is also explained in Section 4.
The scrolling menu that appears during the manual paused state
can have two extra options when using extended programming:
Adjust Enable – This option is available for extended sampling
programs that have programmed enable conditions. Selecting
this option allows you to change the set-points or ranges for the
enable conditions. The sampler displays all of the programming
screens that define the thresholds of the programmed enables.
You cannot change the type of enables used or the way they are
combined.
If rain is an enabling condition, you also have the option of
resetting the rain history.
Pause and Resume Screens
Flowcharts containing the pause and
resume screen appear in Appendix
